Caffé Miani (A.K.A. Zucca In Galleria), Milan

Concierge.com's insider take:

Though there are other bars (and even—the horror, the horror—a McDonald's) inside Milan's glorious Belle Époque shopping mall, the Galleria Vittorio Emanuele, this historic aperitivo stop is the original, and still the best. Now listed as a historic monument, the bar has been here ever since the arcade itself opened in 1867, and in its early days it attracted such luminaries as Verdi and Toscanini. The famous entrance sign promoting Zucca, a rhubarb-based amaro liqueur, gives the bar the unofficial name by which most locals refer to it. The glorious Art Nouveau decor continues inside, with an inlaid wooden bar created by a celebrated Milanese cabinetmaker, cast-iron chandeliers, and lush botanical mosaics by Liberty-era artist Angelo d'Andrea. Order a Campari scecherato—a Campari soda roughed up in a cocktail shaker with ice and lemon; for real Milanese kudos, develop a taste for Zucca itself, which is currently trying to change its image from grandmotherly digestivo to smart young aperitivo.
